The documentation for FoundationDB's Document Layer is lacking on this front. I am looking to use mongorestore || mongoimport with Document Layer so I can start interfacing with FDB.
@openland/foundationdb is the Node.js package I am looking to use within my project, if that helps.
mongorestore --port 12345 ~/Desktop/dump-2019-06-25is how I did it. I'm not sure how to view my databases within FDB but at least I answered this question.
